Solubility and Density Isotherms for the Sodium Sulfate ...

The solubility of sodium sulfate in water and aqueous methanol has been determined over the temperature range 10 °C to 50 °C. Also the saturated solution densities were measured. The presence of methanol was observed to reduce the solubility of the salt greatly. In fact, in pure methanol, sodium sulfate was essentially insoluble. The solubility data for the sodium sulfate−water solution ...
